Life Test Apparatus for AC Contactor
Main application:
It is mainly used to simulate the long running life test of
aftermarket ac contactor contacts.
Technical specifications:
1. Able to conduct electrical life test for single-phase and
three-phase ac contactor contacts
2. 5 station work at the same time, at the same time in the same
load according to the set sequence, set a time with the same load
successively connected or breaking, such as N1 breaking load moment
N2 samples from off state immediately (switch time delay large 0.5
1 second) into connected with load, N1 - N5 so on circulation, five
station test data independent of any Settings and display
3. Count the number of on-off test at each station. When any test
sample fails (normally open or normally closed), the system will
automatically disconnect the load and coil control voltage of the
failed sample without affecting the normal test of other samples
4. time resolution: 0.01 seconds, on and off time according to the
need to set arbitrary
5. Setting range: 0 ~ 100 seconds continuously adjustable
6. The number of trials can be preset arbitrarily, and the counting
range of the number of trials should be less than 1 million times
7. Load current: 100 ~ 200A continuously adjustable, voltage 220V,
power factor 0.3~1 continuously adjustable
8. Coil voltage: ac 24V, 48V, 120V and 220V gears are adjustable
9. the equipment to adapt to the working environment temperature: 0
-- 40℃
10. The load box is equipped with the functions of excessive test
temperature alarm, power off protection and overcurrent protection
11. All test data are designed with power failure protection
function
12. electrical insulation and safety must meet the requirements of
** related standards
13. Main configuration requirements are as follows:
- digital display output voltage value, current value, power, power
factor, instrument accuracy: 0.5 level
- current output mode: R and L are two choices.
- the test cabinet for sample installation must be safe and
reliable
14. The five test stations must be equipped with test fixtures and
connecting wires
15. Power cord bending machine: bending Angle is 0-180°, bending
frequency is required to be 60 times /min
16. One electronic wire bending test bed is used
Operating environment requirements:
temperature at the place where the equipment is used: -10℃~50℃
The humidity of the place where the equipment is used is 10%-100%
Input power: power AC 380v, 50HZ, voltage fluctuation range ±10%.
Working hours: 24 hours.
